FFmpeg Java

ffmpeg-cli-wrapper by Andrew Brampton 2013-2014, upgraded dependencies and added additional features by Dean Gostiša and Roman Orač in 2015.

Added features

We added support for (check examples in unit tests):

• additional transcoding parameters,
• creating thumbnails from input video,
• getting a dominant color of created thumbnail (with Color Thief),
• trim videos,
• stitching multiple videos with fade in, fade out effects, text, text box and video overlays.

Requirements

Install static build ffmpeg to use all added features.

Setup

<dependency>
    <groupId>com.spikeify</groupId>
    <artifactId>ffmpeg</artifactId>
    <version>check for latest version</version>
</dependency>

Usage

Init FFmpeg

FFmpeg ffmpeg = new FFmpeg("/path/to/ffmpeg");
FFprobe ffprobe = new FFprobe("/path/to/ffprobe");

Create thumbnails

FFmpegBuilder builder = new FFmpegBuilder().setInput("inputVideo")
                .setVideoTumbnails(10) //number of frames to extract
                .addOutput("thumbnail-%03d.jpg")
                .done();

FFmpegExecutor executor = new FFmpegExecutor(ffmpeg, ffprobe);
FFmpegJob job = executor.createJob(builder);
job.run();

Get dominant color

File img = new File("image.png");
BufferedImage image = ImageIO.read(img);
String dominantHex = ColorThief.getDominantHex(image, 1, true);

Stitching multiple videos

List<VideoObject> videoObjectList = new ArrayList<>();

//settings for video 1
Caption caption1 = new Caption.CaptionBuilder("someFont.ttf", "Text").setColor("white").setSize(40).setX(50).setY(50).createCaption();
VideoObject videoObject1 = new VideoObject.VideoObjectBuilder("video1.mp4").setFadeIn(new FadeIn.FadeInBuilder(0, 1).createFadeIn()).setFadeOut(new FadeOut.FadeOutBuilder(1, 1).createFadeOut()).setCaption(caption1).createVideoObject();
videoObjectList.add(videoObject1);

//settings for video 2
VideoObject videoObject2 = new VideoObject.VideoObjectBuilder("video2.mp4").setFadeIn(new FadeIn.FadeInBuilder(0, 1).createFadeIn()).setFadeOut(new FadeOut.FadeOutBuilder(1, 1).createFadeOut()).createVideoObject();
videoObjectList.add(videoObject2);

ffprobe.setDuration(videoObjectList); //set duration to each video

FFmpegBuilder builder = new FFmpegBuilder().overrideOutputFiles(true).addOutput("output.mp4").stitchVideos(videoObjectList).done();
FFmpegExecutor executor = new FFmpegExecutor(this.ffmpeg, this.ffprobe);
FFmpegJob job = executor.createJob(builder);
job.run();
